    <p>I have an NSAnimationContext (just a scrolling view) that I would like to slow down and/or pause whenever the cursor enters the view. I have already implemented the detection for when this happens - now I just need to figure out how to slow down the animation that is already in process. I have figured out how to do this with CALayers - but I need to use the animator proxy unable to use several AppKit views within this animation so Core Animation will not work. Does anyone know how to do this? Is there a way to keep track of NSAnimationContexts and then change them later on?</p> <p>Here is a subsection of my code, The first block is cyclicly called. Everytime one agnation completes the next will begin.</p> <pre><code>[NSAnimationContext runAnimationGroup:^(NSAnimationContext *context){ context.duration = pixels/speed; [[currentTweetView animator] setFrame:endRect]; } completionHandler:^{ [currentTweetView removeFromSuperview]; currentTweetView = nil; [self nextAnimationWithAnimationIndex:currentIndex]; }]; </code></pre> <p>Here is the code in the mouseEntered: method. Whenever this is called, neither completionHandler is ever called and the app freezes. </p> <pre><code>[NSAnimationContext runAnimationGroup:^(NSAnimationContext *context){ [[[self.subviews objectAtIndex:0] animator] setFrame:finalRect]; context.duration = 100.0; } completionHandler:^{ NSLog(@"done"); }]; </code></pre> <p>Also, is there any way to end an NSAnimationContext early and not call the completion handler?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
